So would you say math/philosophy would be useful in more of a research type position? In that case you would probably need even higher levels of math - so the logic behind philosophy might be useless either way?
Applied math is very useful to software engineering and many other fields. However, I majored in pure math, which is not useful. Philosophy is interesting (depending on your personality) but is mostly irrelevant. Philosophy major logic courses will help you ace the LSAT if for some reason you want to go to law school.
